Sen Paul responds to attacks from Chris Christie

Tonight, Sean Hannity had Senator Rand Paul as a guest to respond to direct attacks from Gov. Chris Christie. Both are likely contenders for the Republican nomination in 2016. It’s worth noting that Sean Hannity keeps repeating the term ‘libertarian.’ Is this a way to subtly marginalize Senator Paul in the eyes of some Republicans? Does the average Fox viewer know the difference between “libertarian” and “Libertarian?”
